14 GBX24 VME 24 Port Gigabit Ethernet Switch
CAUTION
The GBX24 requires air-flow of at least 300 feet/minute for build levels 1 and 2, and at least
600 feet/minute for build level 3.
WARNING
Class 1 laser product. Invisible laser radiation may be emitted from the connector aperture when no
fiber cable is fitted, avoid exposure by not looking into the open aperture.
CAUTION
Only handle the board by the edges or front panel.
CAUTION
Do not remove the heatsink. There are no user-alterable components underneath the heatsink, so
users should have no reason to remove it. Users should not attempt reattachment of the heatsink, as
this requires precise torque on the screws attaching the heatsink to the PCB. Over-tightening the
screws may cause the heatsink to damage components beneath it. Removal and re-attachment of the
heatsink should only be carried out by the factory.
